Smog pump

Me again...

This '88 of mine (351W) was bought recently and the smog pump has been removed. I've got hoses just hanging everywhere... I'd be willing to bet that this could be one reason it doesn't idle very good? Maybe a reason why I am lacking a lot in power?

Should I:

-plug all the hoses?
-leave them all open?
-replace the pump?
-take the plow off the front and give the truck away?

Thanks
Ryan

Replace the pump. If you run the vehicle very long without an air pump it will damage the catalytic converter. That is, if it is still installed.

Did not read your whole thread carefully. The converter may be plugging up causing the lack of power.

Smog pump

the converter is new, so I know that being plugged isnt the problem. However, it appears as though the tube that goes from the engine to the cat is not attached. In fact, the cat doesn't appear (and I looked very carefully) to have a place for the tube to hook into. Any ideas?

I hate getting myself into messes like this. I bought this truck because it was cheap (a good deal, I thought)... but now I am too caught up in it to even think of selling it. I have vacuum lines that I just discovered were melted shut, I have hoses hanging around in my engine compartment, and it seems as though it's impoossible to route the plug wires around the emissions piping so that the wires don't melt.

Hey, thanks for any help. Maybe I should post a picture of exactly the "garbage" that I'm working on. The only good thing about this truck is the oval emblem on the front grille.

i hate the crap they put on newer trucks these days. they might as well put a modem in the eec computer box so so people can go online and discuss problems on fte while driving the truck, LOL.

Smog pump

My pump locked up on me at work one day, so I pulled it off the truck and took it inside the shop and gutted it. I left the rear bearings in it, so now it is just a idler pully. The vacuum lines from it I just plugged off, and the pipe across the rear of the heads I took to the local hardware store and found a pipe plug that fit it (3/4" pipe?). If you found tubes melted/disconnected, start there and if you don't want the pump, plug them off at the solenoids or the source (manifold?). I know the egr solenoid is right beside them, so trace the tubes to get the right ones. I have codes set for thermactor system failure, but the check engine light seems to have been removed by the previous owner.
Hope this helps.

You can also get the plug inserts that screw into the back of the head from Ford. That way you can take that piping completely off and clean up the engine bay a little.

Smog pump

If I did get the plugs from Ford and plugged those ugly and hard-to-route-wires-around pipes form the exhaust manifold, would I notice a difference in the way the truck runs (compared to how it SHOULD run?) Would it not pass inspection due to emissions system modification?

The problem that I am feeling in the truck is a power loss... In fact, it seems as though the distributer isn't advancing. If I build up momentum and hit a pile of snow with the plow, I can move it no problem. If I try to ease my way into even a small pile and give it some gas, I just sit there and the engine starts to sound terrible. I thought this was possibly a problem caused by the air pump being gone... Does this make sense? I did find a few electrical wires that were melted and/or spliced poorly and I fixed them... haven't had time to fire it up yet, as I have the radiator out of it gettin patched up.

Thanks for all your help so far - I (we) wil get this truck running right this month if it's the only thing I work on
